WRITING-PEN.

Specification of Letters Patent.

Patented Oct. 20, 1908.

Application filed January 31, 1908. Serial No. 413,512.

To all whom it may concern:

Be it known thatl, WILLIAM H. Sonwni znn, a citizen of the UnitedStates, residing at Baltimore city, State of Maryland, have inventedcertain new and useful Improvements in Writing-Pens, of which thefollowing is a specification. A

My invention relates to an improvement in pens, the object being toprovide a writing pen which will write a maximum number of letterswithout refilling, having to a limited degree the qualities of afountain pen, while at the same time it is a pen which may be used withan ordinary pen holder.

With the foregoing object in view, my invention consists in a pen havingwings bent into shape to form cylinders open at both ends, the cylindersbeing provided with a plurality of perforations therein, that the airwithin the cylinders may be readily excluded therefrom when the pen isinserted into the ink, thereby causing the cylinders to become filledwith the ink to a greater degree than they would be otherwise, as moreor less space within thecylinders would be taken up by the air thereincontained, to the exclusion of the ink, thereby lessening the carryingor holding capacity of the cylinders. The cylinders are formed in amanner to provide a space between them; in some instances, owing to theparticular style or construction of the pen, this space is more or lessessential to the effectiveness of the pen while in others it can asreadily be omitted without any material detriment. The space between thecylinders may be located centrally to the slit and hole of the pen or oneither side thereof, so that all combine to hold the ink and pay it outas it is required in the operation of writing.

My invention further consists in certain novel features of constructionand combinations of parts, which will be hereinafter described andpointed out in the claims.

In the accompanying drawings, Figure l is an elevation of a penembodying my invention; Fig. 2 is the blank before being perforated;Fig. 3, is a similar view after it is perforated, and Fig. A is a crosssection on line w00 of Fig. 1.

A represents the body of the pen, having the usual concavity throughoutits length, it being preferably rounded at one end where it enters thepenliolder and pointed at the other end. It may be made in variousshapes and styles. The pointed end 1 has the usual slit 2 and orifice 3,whereby the pen is divided into the nibs 4.4c. At the sides the wings5-5 are formed, preferably, as an integral part thereof, the forwardends of the wings are sharp and pointed, as at 6-6, extending well downtoward and under the point of the pen. In the completed pen not only isthe body portion concaved in the usual fashion, but also the wings areformed up until their edges lie against the concaved surface of the penthus forming the cylinders 7-7 these are perforated at 8 andare open ateach end and preferably approach each other closely, leaving a space 9more or less narrow between them, while their lower ends taper, asshown, the points 6-6 extending well down toward and under the point 1of the pen in order to supply the ink evenly to the point of the pen. Inthis way a pen is formed which carries a large supply of ink, which inkis made to flow gradually along the points of the pen as it is requiredfor writing, each of the cylinders and the orifice 3 contribute to-holdthe ink and to supply itas required, the perforations 8 not onlyincrease the carrying capacity of the cells but contribute materially incontrolling an even flow of ink at the point 1.

Slight changes might be resorted to in the form and arrangement of theseveral parts described without departing from the spirit and scope ofmy invention, and hence I do not wish to limit myself to the exactconstruction as herein set forth.

Having fully described my invention, what I claim as new, and desire tosecure by Lettors Patent, is

1. A pen of the character described, comprising a body part providedwithperforated integral side wings, the said side wings being pointed onthe forward ends thereof and formed into open-ended cylinders beneaththe under side of the said body part, with the said points extended welldown and under the point of the said body' part, sub stantially asdescribed.

2. A pen of the character described, comprising a body part havingperforated integral side wings which are formed into openended cylindersbeneath the under side of the pen, substantially as described.

3. A pen of the character described, comprising a concaved body partpointed on one end thereof, and having a slit separating the point intonibs and terminating in an orifice provided in the said body part,integral perforated side Wings formed into cylinders In testimonywhereof I affix my signature vI'ithlin the said concaved blody part3,each of in presence of two Witnesses. t1e ower ends of the saic win 'sein tapered to a point, Which points a re extei lded WILLIAM SOHWVEIZER'5 Well down and under the point provided on Witnesses:

the said body part, substantially as de- E. WALTON BREWINGTON, scribed.MARY M. MAGRAW.
